Health condition
Health condition(s) or problem(s) studied:
Bioequivalence study conducted in healthy volunteers comparing two formulations of voriconazole with no health condition or problem studied.

Although this study is being conducted in healthy volunteers who are not being treated for the condition to which the medicine is used, voriconazole belongs to a class of medicines called a triazole antifungal agent and is used for the treatment of invasive aspergillosis, candidemia and disseminated candidiasis in skin, abdomen, kidney, bladder wall and wounds, esophageal candidiasis and serious infections. 291303 0

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Single dose, crossover over study design whereby each participant receives the test formulation of voriconazole (1 x 200 mg ) on one occasion and the innovator formulation of voriconazole (1 x 200 mg) on one occasion with each dose seperated by a one week washout period. The intervention for this trial is the test formulation of voriconazole.

Each dose (1 x 200 mg) will be taken orally with 240 ml of water at ambient temperature. Medication must be swallowed whole and a mouth check will be conducted to ensure the medication has been taken as directed.

No water is allowed for 1 hour prior to dosing until 1 hour after dosing (except for the water consumed with the dose).
Participants are required not to eat for 10 hours before receiving each dose and to fast for approximately 4 hours after receiving each dose. Bathroom visits will be supervised to ensure no unauthorised water or food intake and for personal safety. Participants will be confined at the Clinical Site for 10 hours prior to dosing to ensure compliance and will be monitored and for 24 hours after dosing.

Standard meals will be consumed at the Clinical Site with no additional food intake allowed. Alcohol breath testing will be performed upon each participant reporting to the Clinical Site 10 hours prior to dosing.

Pre and post study laboratory tests will be completed to assess the healthy of participants along with HIV, Hepatitis and drugs of abuse testing.

Comparator / control treatment
Single dose, crossover over study design whereby each participant receives the test formulation of voriconazole (1 x 200 mg) on one occasion and the innovator formulation of voriconazole (1 x 200 mg) on one occasion with each dose seperated by a one week washout period. The comparator/control for this trial is the innovator formulation of voriconazole.

Outcomes
Primary outcome [1] 291584 0
To compare the bioavailability of voriconazole (as summarised by Cmax and AUC) for the two formulations. All plasma samples will be assayed for voriconazole using a fully validated LC/MS/MS method. Validation will be conducted to comply with EU and FDA guidelines.

Secondary outcome [1] 307124 0
Time to maximum peak concentration (Tmax) and the elimination half life (t1/2). Tmax will be the time where the maximum concentration occurred in the sample points. T1/2 = 0.693/Kel where kel is the terminal elimination rate constant.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All formulations will be labelled as Formulation A and B. The identification of each treatment will only be known to the Managing Director and the Section Head - Trials and Regulatory Affairs.

Each participant will be identified by a 3 digit screening number and a 2 digit subject number. The screening number will be issued once the participant has given written consent to participate in the study and the two digit subject number (randomisation number) after acceptance into the study
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation list will be prepared using a computer program for a balanced two-way crossover design.
Masking / blinding
